“…Short-chain fructooligosaccharides incorporated at 0.1%, 0.25% or 0.5% in PF-based diets only led to minor effects on gilthead sea bream (32 g) immune parameters, such as an increase in nitric oxide (0.5%) (Guerreiro et al 2016c) ( Table 5). In European sea bass (60 g), either incorporated in FM-or PF-based diets, 1% scFOS inhibited bactericidal activity and neutrophil relative percentage (Azeredo et al 2017). Increase in plasma nitric oxide and thrombocytes percentage was only observed in fish fed FM-based diets, whereas increase in monocyte percentage was only detected in fish fed PF-based diets.…”

“…In white sea bream (53 g), 1% XOS in PF-based diets also induced an increase in alternative complement activity, lysozyme and total immunoglobulin, indicating a possible enhancement of immune status (Guerreiro et al 2016a). On the other hand, in European sea bass (60 g), 1% XOS in FM-or PF-based diets downregulated immune gene expression in the gut, suggesting that gut health might have been compromised, while it partly enhanced systemic response (Azeredo et al 2017).…”

The increased demand for food fish, together with the banning of antibiotics for fish growth promotion and the greater public awareness for healthy fish production, led to an increased interest in the potential of functional feeds as health promoters. Prebiotics are functional ingredients that are used in fish, being reported to be associated with improvements in growth, feed efficiency, gut microbiota, digestive enzyme activities, gut morphology, immune status, disease resistance, intermediary metabolism, and stress responses. Those benefits may be related with the increase in gut beneficial bacteria, bacteria end‐products of prebiotic fermentation, or the interaction between prebiotics and pattern recognition receptors. Due to the reported prebiotic‐related positive effects in fish, a large amount of studies have been published in the last years, mainly focusing on prebiotics’ benefits to fish. Thus, the present review focuses on prebiotics’ potential as functional ingredients, focusing on their mechanisms of action. In addition, this review summarizes prebiotic effects in Mediterranean aquaculture fish, whose production has greatly increased in the last years. Finally, topics that deserve to be further explored, such as prebiotic effects related with fish age and size, and timing and duration of administration are suggested.

“…Although recent studies have shown that it is possible to replace both dietary FM and FO with vegetable sources without compromising sea bass growth performance or survival (see Kousoulaki et al, 2015 for a review), additional studies evaluating the simultaneous replacement of FM and FO in the diet of carnivorous species are still needed (Oliva-Teles, Enes, & Peres, 2015). Furthermore, other implications of this replacement ought not to be ignored, such as nutrient utilization, intestinal morphology alterations, and immune response efficiency (Azeredo et al, 2017;Kokou et al, 2015;Kousoulaki et al, 2015).…”

The inclusion of phytogenics in fish feed is a promising strategy to compensate for the negative performance effects of replacing fishmeal (FM) with vegetable sources. The present work assessed the interactive effects of different dietary FM levels (22.5 and 10% of formulation) and the supplementation of a commercial blend of anise, citrus, and oregano essential oils (Digestarom PEP M.G.E 150) on European sea bass, Dicentrarchus labrax growth performance, nutrient utilization, gut morphology, antioxidant status, and immunological response over a 60‐day growth trial. Results showed decreased growth and protein efficiency ratio and increased feed conversion ratio with a low dietary FM level. In contrast, supplementation of the phytogenic product demonstrated improved performance and nutrient utilization together with increased protein and energy retention. Supplementation with the plant essential oils fully compensated for the negative intestinal changes observed in sea bass fed a low‐FM diet but showed little improvement in fish immunological response, except for the 30% increase in lysozyme activity observed in fish fed the low FM‐supplemented diet compared to those fed the standard high‐FM diet. Overall, this study supports the use of this phytogenic product in low‐FM diets as a possible tool to decrease feed costs associated with FM without compromising fish performance, nutrient utilization, and health.
